I have a choate thumbhole stock for sale on the equip exchange. Probably the toughest stock out there for a MAK and installs in the MAK very easily. The chicom AKs do have a nice trigger.
However, if you want the SAR, they are nice also.
I have done the "conversion" on 2 MAK-90s and it is a little tough as the dimensions are a little different than the euro's. Doable of course but you'll need a dremel and a lot of patience to do it right. Mine are nice, though.
Both have a gordontech FCG now and one has a KVAR US buttstock, PG, with a US Bulgy style lower handguard and a steel vented upper handguard.
The other has a Bulgy (shorter) buttstock, US PG, and US handguard set. All of the stock parts took some modifications and fitting, incl the vented steel upper handguard which I just did this past weekend.
I'm not nuts about the gordontech trigger but alot of people like it. It's a single stage trigger with too much take up for me. I tried to install the RSA FCG but the selector didn't fit right with it and I didn't have the dremel then. YMMV.
I put the RSA FCG in my SAR-1 and it is awesome. I may still put that trigger group in my MAK's.
